DRYlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 506,917, dated October17, 1893.

Application led October 11, 1892. Serial No. 448,499. (No'model.)

.To all whom it may concern.-

Beit known that we, JOSEPH J. DE KINDER, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and AXEL S. VOGT, asubject of the King of Sweden and Norway, and a resident of Altoona,county of Blair, State of Pennsylvania, have invented a new and usefulImprovement in Drying-Machines, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,which form a part of this specification.

Our invention has for its object the production of a machine in whichvarious materials may be treated and thoroughly dried, and it isespecially adapted for the drying of what' are known as brewers grains;and our invention consists incertain arrangements and combination ofmechanism whereby the heat is evenly distributed to the material to bedried and is prevented from passing into that portion of the receptacleunoccupied by the material to be dried.

In the drawings-Figure l is a longitudinal section partially inelevation of our apparatus. Fig. 2 is a section on line 1 2, Fig. l.Fig. 3 is a section of one of the pipes. Fig. 4 is a detachedperspective view of a modied form of port closing device. Fig. 5 is asection on the line 3-4, Fig. 4. Fig. 6 is a view similar to Fig. 2 of amodified form of apparatus.

A is the receptacle for the material to be dried,fwhich is preferably aperforated cylinder having doors lor movable portions, A', for theinsertion and removal of the material, and surrounded by a solid casingB having corresponding doors, B B2' C are the steam or other heat-inletpipes. Through the cylinder A passes the conduit or ipe D, which issecured to said cylinder A and opens into the pipe C. This pipe D restsin bearings a. upon the support or stands a', and it is adapted torevolve, and may be revolved by means of the wheel E secured to saidpipe D beyond the cylinder A (Fig. l). Within the cylinder A, openinginto said conduit D and projecting therefrom at an angle to the axis ofrotation of said pipe D, are the perforated pipes F. These pipes aremade in two sections, f, f (see Fig. 3), connected together by thejoints f2, said joints having the inwardly projecting iiange f3, formingwhat may be called a port between the two sections of pipe F.

G is an angle-iron frame, forming a valve, the extent of which isgreater than the width of the port. One end of this angle frame or valveis pivoted to one side of the flangefs, and the projecting portion ofthe angle frame or valve is adapted to rest on lthe flangefs.

H is a rod connected to one arm of the angle frame, and connected at itsother end to an arm f5 projecting from the angle-iron frame or valve G.Upon this rod is the weighted sphere or ball I, through which ball therod H passes loosely. In place of the ball or sphere j being suspendedon the rod H, it`may be placed between the rod H and the an gle-frame(see Figs. 4 and 5). As may readily be seen, as the pipes F revolve, theball I will slide upon the rod (or between the rod and the frame),tilting the frame, and according to the position of the ball, open orclose the port. The closing of the port occurs when the pipe is standinginclined upward in the position projecting upward from the conduit orpipe D, and as the pipe moves downward from the vertical position itopens, the closed position being that where a portion of pipe F projectsbeyond the material to be dried.

Instead of using a single central conduit,a series of conduits or pipesmay be usedfas shown in Fig. 6.

Having now fully described our invention, what we claim, and desire toprotect by Letters Patent, is

l. In a drying machine the combination with a receptacle to receive thematerial to be dried, of a heat conduit extending through saidreceptacle and adapted to rotate with said receptacle, pipes openinginto and projecting from said conduit at an angle to the yaxis ofrotation of said conduit, said pipes being provided internallywith aport, an angle framed valve adapted to cover said port, said angleframed valve being hinged, and a weight upon said frame adapted to moveupon said frame when said pipe is revolved.

2. In a drying vmachine the combination 3. In aV drying machine thecombination- With a receptacle to receive the material to be dried, of aheat conduit extending through said receptacle and adapted to rotatewith said'receptacle, pipes opening into and-projecting from saidconduit atan angle to the axis of rotation-of said conduit, said pipebeing formed in two parts, a joint uniting said parts, said joint havingan internal flange which forms a port within said pipes, an angle framedvalve adapted to cover said port, said angle framed valve being pivotedand a weight upon said valveand adapted to move z 5 upon the frame whensaid pipe is revolved.

4. In a drying machine the combination with a receptacle to receive thematerial to be dried, of a heat conduit extending through saidreceptacle and adapted to rotate with 3o said receptacle, pipes openinginto and projecting from said conduit at an angle to the axis ofrotation of said conduit, said pipes being formed in two parts,ajointwhich unites said parts, said joint having an internal flange 35 whichforms a port in said pipes, an angle 'framed valve Aadapted to coversaid port, said angle framed valve being hinged, a rod or bar .securedto said frame, and a weight through kwhich said rod or bar passes andupon which 4o Ysaid weight is adapted to slide.

In testimony of which invention We have hereunto set our hands.
